This Sunday is World T-B Day, a day to help raise awareness about the health and economic affects of tuberculosis.

The rate of tuberculosis cases in Texas is going down by an average of 4 percent annually. In Travis County, the number of cases has dropped steadily over the past few years after a recent rise in cases. There were 37 cases in 2012, 52 cases in 2011 and 67 in 2010.

Travis County Clinic Manager Rosalinda Castaneda says tuberculosis is treatable, as long as the proper medication is taken.
